IP68 Waterproof Acrylic Dome Cover for Clear and Reliable Optical Access

Reliable Performance in Water or Outdoors
Perfect for Waterproof and Observation Devices
The “Waterproof Acrylic Dome Cover (IP68-rated)” is a dome-shaped cover made of acrylic, equipped with an O-ring for secure sealing.
By integrating it into a waterproof housing, it can be used as a “windowed enclosure” that allows visibility of internal components from the outside—achieving both clarity and reliable waterproofing.

Acrylic dome cover with O-ring attached to the bottom. (Patent pending)
By drilling a hole in a waterproof case and attaching it to the waterproof case, it can be made into a waterproof camera case.
This is useful for all-sky cameras installed outdoors or when you want to check the monitor status of the equipment.
Flange Cover

Cap-Type Flange Cover for Enhanced Sealing and Alignment
The flange cover features a cap-style design that securely fits over the O-ring and acrylic dome cover, holding them firmly in place.
This construction prevents misalignment of components and provides additional support to improve sealing performance and durability.
